International Day of Mathematics 2025
Theme "Mathematics, Art, and Creativity"
The planning has started. You will find information on the activities in Münster in February 2025 on this webpage.
About the international day of mathematics
The International Day of Mathematics (IDM) is a worldwide celebration led by the International Mathematical Union. Each year on 14 March schools, museums, libraries and other spaces in countries around the world will be invited to participate in the celebration through activities for both students and the general public. The International Day of Mathematics was declared by UNESCO during the 40th session of the General Conference, 26 November 2019, and the 14 March 2020 marked the first celebrations.
March 14 was chosen as the date for the IDM because some countries write it as 3/14 and the mathematical constant Pi is approximately 3.14.

Rückblick 14.03.2024
27 Kinder von unterschiedlichen Schulen haben uns am Tag der Mathematik besucht. Gemeinsam mit den Mathematik-Studentinnen Lisa Daldrup und Greta Schonhofen sowie Katharina Harengel und Jule Kalbertod, Doktorandinnen am Exzellenzcluster Mathematik Münster, lernten sie an fünf Stationen spielerisch verschiedene Facetten der Mathematik kennen. Uns hat es viel Spaß gemacht - euch hoffentlich auch!
Spiel und Spaß mit Mathematik
Passend zum Motto "Spiele mit Mathematik" bereiten wir viele spannende Stationen mit Mathe-Spielen für euch vor. Von Brückenbau bis Mathefußball und einem Western-Duell ist alles mit dabei. Außerdem wird eine Schlange der besonderen Art eine Rolle spielen. Neugierig geworden? Dann meldet euch an!
Wann? Donnerstag, 14.03.2024, von 16 bis 18 Uhr
Wo? Orléans-Ring 12, 48149 Münster
Für wen? Schüler:innen der 5. und 6. Klasse - aber auch wenn du etwas jünger oder älter bist, kannst du dich gerne anmelden.
Anmeldung: Anmeldephase abgeschlossen
Die Teilnahme ist kostenlos. Für Getränke und Snacks ist gesorgt.
Wir freuen uns auf euch!

International Day of Mathematics 2021: Mathematics for a better world
"Mathematics for a Better World" - this is the theme of this year's International Day of Mathematics. A good example is medical progress: mathematics makes important contributions, for example for medical imaging. We offer you some insights into this exciting research topic.
Video: "What's Next" with PhD student Marco Mauritz
At first sight, mathematics and cancer treatment don’t have much to do with other. However, calculations play an important part in medical imaging. Marco Mauritz, PhD student in Applied Mathematics, works at this interface in an interdisciplinary team of researchers, helping not only to develop new forms of treatment in cancer research, but also to improve existing ones.

Interview: Mathematics and Medical Imaging - with Prof. Dr. Benedikt Wirth
Prof. Dr. Benedikt Wirth© MM/vl In this interview, Prof. Dr. Benedikt Wirth, Professor for Mathematical Optimisation, provides insights into the mathematical concepts that are fundamental to medical imaging.
He also describes research projects he is currently working on, together with scientists from biology, medicine, physics and other disciplines.
Livestream: "Blick in den Körper: Über das Inverse und medizinische Bildgebung"
Online-Vortrag am 24. März 2021 mit Prof. Dr. Benedikt Wirth
© MM Moderne Technik erlaubt den Blick in den Körper, ohne ihn zu öffnen. Es wird sozusagen berechnet, wie der Mensch von innen aussieht. Um Technologien wie Computertomographie (CT), Magnetresonanztomographie (MRT) oder Ultraschall zu entwickeln, bedurfte es einiger fundamentaler mathematischer Erkenntnisse - die im Nachhinein gar nicht so kompliziert sind. Im Zentrum steht dabei der Begriff des oder der Inversen, was in etwa "Umkehrung" bedeutet.
In seinem Online-Vortrag gibt Prof. Dr. Benedikt Wirth einen Einblick in diese klassischen mathematischen Erkenntnisse.

Mathematics for a Better World Poster Challenge
© 2021 International Mathematical Union Theme 2021 "Mathematics for a better World"
As the world faces the COVID-19 pandemic, mathematics provides its models and tools to help us understand, monitor, and control the spread of the virus. It is also used to create weather forecasts and prepare for natural disasters. It warns us of climate change and helps us to anticipate and mitigate its consequences.
Mathematics is central to the efficient organization of societies for the benefit of all citizens. It optimizes transportation and communication networks and enables smart planning and management of health, economic, and social systems. Science and mathematics have a crucial role in steering decisions to promote peace and social justice.
As a common language to the planet, mathematics is an essential part of humankind’s cultural heritage. It is present in arts, music, and games, for human enjoyment and well-being.
